Entity Biome Spawning

I'm making a datapack that adds new wolf variants to the game and I was wondering is there a way I don't have to touch worldgen code to make a wolf spawn in specific biomes?
Case: I want German Shepherds (wolves in meadows) to spawn in Meadows, is there any work around to editing the biome.json file for meadows? Issue being that each version I'll have to update the file to ensure it fits with the latest patches and tweaks.
